Minnesota for Marriage, the group backing a proposed gay marriage ban in the state, will protest General Mills' opposition to the measure.

Voters in November will decide whether to place the state's law which bans gay nuptials in the Minnesota Constitution.

The food giant announced its opposition to the amendment last week.

“For decades, General Mills has worked to create an inclusive culture for our employees. We believe it is important for Minnesota to be viewed as inclusive and welcoming as well. We oppose the proposed constitutional amendment because we do not believe it is in the best interests of our employees or our state economy,” Tom Forsythe, vice president of corporate communications, said in a statement.

Ken Powell, chairman and CEO of General Mills, expressed similar views at a Gay Pride event.

In an e-mail to supporters, Minnesota for Marriage called the move “stupid” and announced it would be hold four days' worth of “Dump General Mills Rallies.”

“I know it seems odd for a company who spends billions of dollars marketing products to moms and dads with young children to do such a thing, but General Mill has tried to please a small minority of individuals who feel entitled to change the definition of marriage for all of society. They have calculated that we won't fight back. They have grossly miscalculated us!” wrote Andy Parrish, deputy campaign manager for Minnesota for Marriage.

The daily rallies will take place across from the company's Minneapolis headquarters starting on Tuesday, June 26. Supporters are being called on to bring General Mills products from home and dump them in a trailer to be donated to a local food bank.

The National Organization for Marriage (NOM) has also criticized General Mills for its opposition to the amendment. NOM earlier this year launched a “Dump Starbucks” campaign over its decision to support a gay marriage law in Washington state.
